SEWAGE-EJ'EOTING SYSTEM.

To all whom it may concern:

Be it known that 1, JOHN W. GooNnY, a citizep of the United States,residing in theborough of Manhattap, city of-New York, in the county ofNew York and State of New York, have invented certain new and usefulImprovements in Sewage-Ejecting Systems, of which the following is aspecification, reference being had therein to the accompanying drawings,forming a part thereof.

My invention relates to a system and apparatus for transferring liquidsfrom places where liquids accumulate and from which they must beremoved. For instance, my invention is applicable to the purpose ofejecting sewage from a receiving tanker reservoir into a sewer in caseswherein the receiving tank is located below the sewer level, and to thepurpose of ejecting the sewage accumulated in a lreceiving tank locatedon board ship below the water level, and to the purpose of ejectingbilge water from ships, and to other similar purposes. l

The objects of my invention, broadly stated, are reliability and economyof operation, economy and simplicity of maintenance, and simplicity andeconomy of construction.

My invention comprises various features, all of which will appearclearly in the light of the following description of that particularembodiment of my invention which I have illustrated in the accompanyingdrawings; and I will at this point make general mention of several ofsuch features.

My invention comprises a tank provided with a suitable discharge conduitor outlet and arranged to receive the sewage or other liquid-which is tobe transferred or ejected, a float arranged to rise and fall with thelevel of the liquid in the tank, a source of compressed gas arranged tocommunicate with the receiving tank so as to expel or eject the liquidtherefrom, a valve in con-' trol of such communication between thesource of compressed gas and the receiving tank, and an energystoringvalve-shifting spring or equivalent device arranged to be compressed bymovement of the float or otherwise to receive valve-shifting energy fromsuch float movement and arranged to deliver such energy to the valve ina valve-shifting movement so that, after the valve-shifting device hasbeen set by movement of the float, it can operate the valve positivelyand quickly and without dependence upon any further movement of thefloat; and my invention also broadly comprehends a float andvalve-shifting energy-storing device and valve such as above defined,arranged to control communication between the receiving tank and theouter air. My invention also broadly comprehends such a float andenergy-storing valve-shifting device and valve arranged to control bothcommunica- Specification of Letters fatent.

tions above mentioned, to wit, communication between the receiving tankand a source of compressed air and communication between such tank andthe outer air.

As one embodiment of the energy-storing valveshifting device abovementioned, my invention broadly comprehends an extensible or telescopingvalve-shifting spring rod pivotall; .nchored at one end and at the otherend pivotally connected with the valve and having a compression springmounted thereon and arranged to be compressed by shortening of thespring roll, the valve in thisinstance being moved by the float so as toshorten the spring rod and compress the spring so that, after the springhas been thus compressed, it will further shift the valve quickly andfoo positively and without dependence on any further movement 'of thefloat.

Further, the illustrated embodiment of my invention comprises twotelescoping spring rods such as above described, arranged opposite eachother so as to co-act efliciently in receiving energy from the float anddelivering valve-shifting energy to the valve. i

I will now describe the illustrated embodiment of my invention and willthereafter point out in claims the broad and specific features thereof.

The drawings illustrate the adaptation of my invention to the purpose ofejecting sewage from a receiving tank arranged to receive the sewagefrom a building and located considerably below the level of the streetsewer.

In the accompanying drawingsFigure 1 is a general elevation of theentire system and apparatus. Fig. 2 is an elevation of the receivingtank, the ejection controlling valve and piping mounted on the tank, andthe valve controlling float contained Within the tank, the tank itselfbeing shown in midsection and the view point being the same as inFig. 1. Fig. 3 is a midsectional elevation of the receiving tank from-aview point to the right of Fig. 2 and shows the piping mounted on thetank and also showsthe float in transverse midsection. Fig. 4 is asectional plan view of the tank and valve controlling float, the planeof section being indicated by the line 4-4, of Fig. 2. Figs. 5 and 6 areen larged midsectional elevations of the ejection-controlling va: ve,the view point being the same as in Figs. 1 and 2 and the valve of Fig.5 being shown in position to effect ejection of sewage from thereceiving tank, while the valve in Fig. 6 is shown in normal positionpermitting sewage liquid to accumulate in the receiving tank.

The receiving tank 2 is located in the subcellar of a building andreceives sewage water from a drain pipe 3, into which are emptied sinkssuch as 4, water closets such as 5, and wash basins such as 6. The drainpipe discharges into the bottom of the receiving tank at one sidethereof and through an inlet gate valve 7 and also terminal of 'each of'the individual motor-controlling through an inlet check valve 8interposed qetween such gate valve and the tank. A discharge pipe 9leads from the bottom of the receiving tank at a point opposite theinlet from the drain pipe 3, and extends upward to a point of connectionwith the street sewer.

An outlet gate valve 10 is interposed in the discharge pipe 9 near thereceiving tank, and an outletcheck valve 11 is connected in suchdischarge pipe between such gate valve and the tank.

The sewage water is ejected from the receiving tank by compressed airand I have provided two electric motor air-compressors 12-and 13 forsupplying compressed air to the air tank 14. These compressors areconnected to the main air pipe 15 through suitable globe valves 16 and17, by means of which either compressor may be'shut off from the mainair pipe, leaving the other compressor to do the work. The main air pipecommunicates direetlywith the air tank 14 and conveys air to such tankfrom the compressors, and from such tank to the sewage receiving tank 2.On the switch board 18 are mounted the fuses 24 and the switches 19, 20and 21, which control the electric motors of the compressors 12 and 13;and on such switch board are also mounted a pressure gage 22 indicating.

terminal of each of the individual motor-controlling switches 20 and 21,while the opposite side of the power circuit leads from the switch 19through the pressurecontrolled circuit-breaker 23 and thence to'an'opposite switches. The motor-controlling switch 20. is interposed inthat branch of the power circuit which feeds the electric motor of thecompressor 13, while the motor-controlling switch 21 is interposed inthat branch of the power circuit which feeds the electric motor of thecompressor 12. A small switch-board pipe 26, mounted on the switchboard, is connected with the main air pipe 15 through a hand-controlledcut-off valve 27. The switch-board pressure gage 22 and thepressure-controlled circuit-breaker 23 are directly connected with theswitch-board pipe 26, and a-blowoff or puppet valve 28 is also connectedwith such switch-board pipe 26 and adjusted to blow off-at a givenpressure to insure against bursting of the air tank 14 or other damageincident to rise of pressure in the event of failure on the part of theautomatic pressurecontrolled circuit-breaker 23 to. stop either or bothof the electric compressors when a predetermined pressure has beenattained in the air tank and main air pipe. The foregoing organizationof air tank, compressors and switch-board apparatus operates to maintaina supply of compressed air within the tank.

We may now consider the construction of the ejection-controlling valvedesignated generally by the reference character 29. The valve propercomprises upper and lower valve pistons 30 and 31 respectively, mountedon a common valve stem 32 and reciprocating in a cylindrical valvechamber 33 provided with connec- -s es,seo

tion lugs 34 and 35 bored to form valve ports and communicatingrespectively with the main air pipe 15 and with the sewage tank serviceair pipe 36 which leads directly into the top of the sewage tank 2.Handoperated cut-off valves 37 and 38 are interposed respectivelybetween the valve-connection lug 34 and the main air pipe 15 and betweenthe valve-connection lug 35 and the sewage tank service air pipe 36.These hand valves are normally open. The upper end of the cylindricalvalve chamber 33 is directly connected with a vent pipe 39 leading tothe outer air. A normally closed hand-operated cut-off valve 40, whenopened, connects the sewage tank service air pipe 36 with this vent pipe39. A normally closed hand-operated cut-off valve 41, when opened,connects the' main air pipe 15 directly with the top of the sewagereceiving tank 2.

The normally closed cut-off valves 40 and 41 are designed to operate thesewage ejecting, apparatus by hand when, for the purpose of repair orinspection, it is necessary to remove the ejection-controlling valvewhich generally controls the operation of the apparatus automatically.In the event of such hand control, the normally open hand operatedvalves 37 and 38 are closed as long as the automaticejection-controlling valve is r'emoved, and while sewage flows into thetank from the drain pipe 3 the hand valve .40 is opened to permit theair in the upper part of the tank to escape freely into the vent pipe 39and the hand valve 41 is closed to prevent the escape of compressed airfrom the main air pipe 15. Then, after, the tank has filled'with sewagewater, the hand valve 40 is closed to cut off communication between thesewage tank 2 air is admitted into the sewage t nk. After the tank hasthus been emptied, the hand valve 41 is closed and the hand valve 40 isagain opened to permit escape of air from the sewage tank 2 and thuspermit the tank to receive sewage water from the drain pipe 3. The inletand outlet gate valves 7 and 10 are provided to close the ends of thedrain pipe 3 and discharge pipe 9 i when it'is desired to remove theinlet and outlet check valves 8 and 11.

The cylindrical valve chamber 33 is mounted on an open frame casting 43provided at its lower end with an integral stufling box inserted, asindicated, into the top of the sewage tank 2. The valve stem 32 passesdown between the diametrically opposite legs of the open frame 43 andthrough the stufiing box and into the upper end of the sewage receivingtank. The'lower and upper valve ports formed respectively in the valve Ilugs 34 and 35, and the valve pistons 31 and 30, are so positioned thatwhen the valve is in its lower or normal position-indicated in Fig. 6,the lowerport in the lug 34 is closed and the upper port in the lug 35is in open communication with the vent pipe 39 leading into the upperend of the cylindrical valve chamber, while the valve in its uppermostposition, indicated in Fig. 5,

closes such communication between the upper valve port and vent pipe andopens communication between such upper valve port and the lower Valveport.

On that portion of the valve stem which passes through the open .frame43 is mounted a valve stem collar 44 provided with diametricallyopposite lugs pivotally connected with the inner ends of spring rods 45which are slidably fitted into spring sleeves 46 pivoted at their outerends to lugs formed on the inner sides of the opposite legs of the frame43. The inner ends of the rods and the outer ended the sleeves 46 becoincident so that they will exert no longitudinal thrust upon the valvestem. This position of the spring rods may be designated the neutralposition, and when the valve stem is above this position it will besubjected to an upward thrust from the spring rods, and when the valveis below such neutral position it will be subjected to a downward thrustfrom the spring rods, all by virtue of the composition of concurrentforces well known in physics.

The top and bottom of the sewage receiving reser voir are stiffened bytransverse angle irons 48 and 49, respectively, and stayed by twovertical iron strips 50 riveted at their ends to such top and bottomstiffening apglcs 48 and 49. A hollow cylindrical float 52 floatsbetween the vertical stays 50 upon the sewage liquidin the sewage tankand, of course, rises and falls with the liquid in the tank. A verticalfloat rod 54 passes freely through a middle diametric bushi g 53 fixedin I the hollow cylindrical float. The floatrod 54 is guided havereached the neutral position.

at its lower end in a bracket 51 mounted on the bottom stiffening angleiron '49, and the upper. end oi the float rod is connected with thelower end of the valve stem 32 by a universal joint 57. The float rod54, together with the stays 50, guide the float in its rising andfalling movement. The float rod 54 carries upper and lower strikingcollars 55 and 56 respectively, which are engaged by the upper and lowerends of the bushing 53 as the float is carried by the rise and fall ofliquid to its uppermost and lowermost positions.

While the sewage receiving tank 2 is being filled from the drain pipe 3,the ejection-controlling valve and its valve stem 32 are in lowermostpositions indicated in Figs. 1, 2, and 5. As the sewage accumulates inthe tank 2, the float rises with the sewage level and until the upperend of the guide bushing 53 comes into contact with the upper strikingcollar 55 on the float rod 54. Thereafter further rise of liquid causesthe float to raise the upper striking collar 55 and thus raise the floatrod 54 and the valve stem 32 until the spring rods upper end of theupper valve piston 30 is just above the upper valve port, while thelower end of such upper piston is just below such upper valve port, sothat the up At this instant the per valve port is effectually closed. Atthis instant the lower valve port is also effectually closed because itcommunicatesonly with the space between the two valve pistons andbecause such space is not, at the moment in communication with the uppervalve-port. Now, any further rise of liquid in the sewage receiving tankwill cause the float to raise the valve stem 32 withits-tclescoping'spring rods above their neutral position, whereupon thespring rods will immediately throw the =valve quickly and forcibly toits extreme .upward position where the upper valve piston 30 abutsagainst the upper end of the cylindrical valve chamber. In thisuppermost position of the valve, both itsupper and lower portscommunicate with the space between the upper and lowervalve pistons andhence communicate with each other so that compressed air immediatelyflows from the main air pipe 15 through the normally open hand valve 37,lower valve port, space between the upper and lower valve pistons,upper valve port, normally open hand valve '38, and the sewage tankservice air pipe 36 into the upper end of the sewage tank. Thecompressed air thus admitted to the upper end of the sewage tank quicklyexpels the sewage liquid from the tank by way of the outlet check valve11, outlet gate valve 10 and discharge pipe 9; and as the liquid levelin the tank falls, the float, of course, falls with it until the lowerend of the float guiding bushing 53 engages the lower striking collar 56on the float rod 54, so that further iall oi liquid will result incarrying the float rod and valve stem downward until the telescopingspring rods connected with the' valve stem are again in neutralposition. As the float is iallingand just before the telescoping springrods are brought to neutral position the upper valve piston 30 closesthe upper valve port and thus severs communication between the main airpipe 15 and the sewage tank service air pipe 36, but when this closureof the upper valve port occurs, the-greater part oi sewage has beenexpolled from the tank so that the tank contains a large quantity ofcompressed air which, by its expansion, continues the ejection of sewageand the falling movement oi the float until, as before noted, thetelescoping spring rods assume their neutral positions. And thereafter avery slight continuance of fall of liquid level and float results incarrying the spring rods below their thrust the valve stem, pistonvalves, float rod, etc, to

lowermost positions indicated in Fig. 6 so as to close the lower valveport and open the upper valve port communication with the vent pipe 39by way oi the cylindrical valve chamber. Thereupon the compressed airescapes irom the sewage receiving tank by way of the sewage tank serviceair pipe 36, normally open hand valve 38, 'upper valve port, cylindricalvalve chamber, and vent pipe 39, and the tank is now in condition to befilled again from the drain pipe 3.

The universal joint 57 is provided to allow for inaccuracy in alineinentof the valve stem 32 and the float rod bracket 51.

' The functions oi'the telescoping spring rods and the importance ofemploying such telescoping spring rods,- or some equivalent thereof,will be apparent from the foregoing description. 7 By positively andquickly throwing theejection-controlling valve to either of its extremepositions and without any considerable moveneutral positions, whereuponthey forcibly and quickly v iso ment of the float beyond that requiredto bring the telescoping spring rods to neutral positions, this deviceeffects that positiveness oi control of the compressed air which isnecessary to alternately eject the sewage with positiveness from thetank and permit such sewage to flow freely into the tank.

It will be apparent that my invention and various distinctivefeaturesthereoi may be embodied in various constructions andarrangements specifically different from the illustrated embodiment ofmy invention but coming, fully within the scope, principles and spiritthereof.

What I claim is:-

A system for transferring liquids comprising a tank arranged to receivethe liquid and provided with a suitable outlet, 21. float arranged torise and fall with the liquid in the tank, a ventway aifordingcommunication between the tank and the outer air, a source of compressedgas in communication with the tank, a vertically-movable piston valve incontrol of both such communications, 13, valve rod connected with thevalve and entering the top of the tank, connections between the valverod and the float whereby the rod and valveare raised and lowered by themovements of the float, and spring-actuated valve-shifting mechanismconnected with the valve rod and operating to open and close the valvequickly during the latter portions of the vertical movements of thevalve rod.

In testimony whereof I have aflixed my signature in presence of twowitnesses.
